我创建了一个upload.php文件，其中包含一个HTML表单和上传图像所需的PHP代码，我使用XAMPP localhost：
htdocs/web2/assets/upload.php
我想将图像上传到同一目录中的upload文件夹：
htdocs/web2/assets/uploads/
<?php
<form action="?" method="post" enctype="multipart/form-data">
<!--wrap input button as around pre-existing image -->
<?php
echo '<label class="profile_gallery_image_in"><input type="file" name="fileToUpload" id="fileToUpload" onchange="form.submit()"/><p class="label"></p><img class="myImg" src='.$image.' height="100%" width="100%" /></label>';
?>
</form>
<!-- Commence Photo Upload -->
<?php
$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
?>
表单设置为在输入类型更改时自动提交。这似乎工作正常，表单正在提交。
但是，我没有上传任何实际图像，也没有任何错误。
我该如何解决这个问题？
代码中似乎有错误。您可以使用以下代码进行图片上传。
<?php
if(isset($_FILES['image'])){
$errors= array();
$dir = "images/";
$file_name = $_FILES['image']['name'];
$file_name = $dir. $file_name;
$file_size = $_FILES['image']['size'];
$file_tmp = $_FILES['image']['tmp_name'];
$file_type = $_FILES['image']['type'];
$tmp = explode('.',$_FILES['image']['name']);
$file_ext=strtolower(end($tmp));
$extensions= array("jpeg","jpg","png","gif");
if(in_array($file_ext,$extensions)=== false){
$errors[]="extension not allowed, please choose a GIF, JPEG or PNG file.";
}
if($file_size > 2097152) {
$errors[]='File size must be excately 2 MB';
}
if(empty($errors)==true) {
move_uploaded_file($file_tmp, $file_name);
echo "Success";
}else{
print_r($errors);
}
}
?>
